Integrated energy system(IES) provides an important platform for efficient synergy and complementary utilization of multiple energy sources. The source-grid-load-storage dynamic modeling technology is an important factor for IES to realize dynamic multi-time scale simulation and optimization calculation

and is also a necessary prerequisite to ensure safe and stable operation of the IES. This paper introduces the main dynamic models of source-grid-load-storage side of the IES and uncertainty models of the IES. On this basis

it analyzes the current status of the application of source-grid-load-storage dynamic modeling techniques in the unified modeling research and framework

and outlooks the development direction of dynamic modeling. The result shows that

various types of dynamic models of source

grid

load and storage need to be further balanced in terms of accuracy and time complexity

thus to be further introduced into the unified dynamic modeling framework

and eventually build a unified simulation platform and digital twin system.
